Update 01.05.18:

Just a quick look into the hive. Bees are doing what the do best: Glueing every void shut with wax :) They even fixed the dangling Si7021:

Everything else is in best order. Logger hasn't gone into fail-mode and is logging away... I'll replace the micro SD card next saturday to check if all the data is logged properly.

We took two (female) brood combs out of one very active and healthy hive and put them into a new box. We add one honey comb and a water comb as well:

Above: from left to right: water comb, honey comb, two brrod combs.

Next, the sensors are put in place:

Under the stainless plate is the Si7021 to keep the right side down. One temp. sensor is left in the void to the left, another one right beside their entrance (wire in the upper right corner).

We add a piece of plastic foil on top and close the lid. The logger is powered on and the case is tightly closed with 4 screws:

The case is IP67 proof but I added a bag of silica gel to be sure no water harm the sensitive devices.

DONE!

We won't interrupt them anymore for the next few weeks now but I'll keep you up to date anyway.

Cheers, Jan
